If your business operates in Rajasthan, GST State Code 08 is one of those small details that has a big impact. In India, the first two digits of your GSTIN identify the state of registration, and for Rajasthan, that code is 08.
Using the correct code matters for GST registration, invoicing, and return filing. This is because it helps the GST system validate your location and apply the right tax based on the transaction.
In this guide, we’ll break down where and how GST State Code 08 is used, so your business stays accurate and compliant.
What is GST State Code 08?
GST State Code 08 is the two-digit identifier assigned to Rajasthan under the GST system. It appears at the very start of every Rajasthan-registered business’s GSTIN. So, a typical GST number begins with “08”, followed by the taxpayer’s PAN and other digits that uniquely identify the registration.
In simple terms, the Rajasthan GST code helps the GST portal and tax authorities recognise where your business is registered and process your tax data correctly. It’s used during GST registration in Rajasthan and also while generating invoices and filing returns, because the state code supports accurate classification and validation of GSTIN details.
How GST State Code 08 impacts your business in Rajasthan
GST State Code 08 helps the GST portal recognise that your registration belongs to Rajasthan and process your invoices and returns accordingly. Here’s why that matters in real business terms:
It influences which GST you charge (CGST/SGST vs IGST)
GST depends on the location of the supplier and the place of supply. If the state details are captured incorrectly, a transaction that should be intra-state can get treated as inter-state (or vice versa). That can lead to incorrect tax collection and messy reconciliations later.
It keeps your filings cleaner and easier to match
In Rajasthan GST filing, invoice-level details get matched across the system (between supplier and buyer). When state codes and GSTINs are right, you reduce the chances of avoidable back-and-forth or corrections.
It supports day-to-day compliance discipline
Using GST State Code 08 consistently across documents helps maintain GST business compliance in Rajasthan by cutting down on “small” errors that often become “big” problems during return filing or scrutiny.
Importance of correct GST State Code in invoicing
On an invoice, the state code defines how the supply is to be classified under GST. For inter-state invoices, businesses need to mention the place of supply, along with the state name and its code. That’s where the GST state code in invoicing becomes especially important.
For example, if you’re issuing a GST invoice in Rajasthan for a business in another state, the buyer’s state code will help the transaction get correctly classified as inter-state and taxed under IGST. Inter-state supply is when the supplier is in one state, and the place of supply is in another.
If your team frequently raises invoices, it is helpful to keep a reliable state-code reference handy (especially when onboarding new customers or updating templates). TallyPrime’s state code list is a simple resource you can use as a quick cross-check.
How to register for GST using State Code 08
This is how you can easily register for GST Rajasthan with the right state selection:
Step 1: Visit the GST portal
On the GST portal, navigate to Services, then click on ‘Registration’. Select ‘New Registration’ to start the application.
Step 2: Fill out Part A
Enter your details such as PAN, mobile number, and email ID. Select Rajasthan as the State/UT. You’ll receive an OTP for verification. After confirming, you’ll receive a Temporary Reference Number (TRN) to continue.
Step 3: Fill Part B
Log in using the TRN and enter business details, promoters/partners, authorised signatory, and principal place of business (district/pin based on your Rajasthan address). Upload any required documents and confirm with DSC/EVC.

After submitting the application, you can track the status on the portal. Once approved, the GSTIN assigned for Rajasthan will carry “08” at the start.

GST returns filing with State Code 08
Here’s how most businesses file GST returns in Rajasthan on the official portal:
- For GSTR-3B, go to ‘Services’ on the official GST portal. Then, click on Returns. On the Returns Dashboard, select the period, prepare the return, and submit it.
- For GSTR-1, the form is to be filed monthly/quarterly based on eligibility/options.
If your invoices correctly capture supplier/buyer GSTINs and place-of-supply details, your return filing becomes far smoother. This is because the portal can validate and classify transactions more reliably, and you reduce the chance of avoidable mismatches later.
Common mistakes to avoid when using GST State Code 08
Here are a few GST filing errors Rajasthan businesses should watch out for:
- Using the wrong state in the customer invoice template: If a buyer is mapped to the wrong state, your invoice may reflect an incorrect place of supply. That can push you into charging the wrong tax type, which then creates reconciliation issues in returns.
- Entering an incorrect GSTIN/state code combination: Since the first two digits of GSTIN reflect the state code (and 08 is Rajasthan, an incorrect GSTIN can cause invoice mismatch and input credit delays for your buyer.
- Not fixing mismatches promptly: Small invoice-detail mismatches can snowball into bigger return-level reconciliation issues, especially between outward supplies and the tax paid/declared.
And yes, the GST law even includes penalties for offences such as issuing an incorrect/false invoice or short-payment of tax.
Final take
GST State Code 08 influences how your registration is identified, especially when you’re selling outside the state. And for inter-state supplies, invoices must capture the place of supply along with the state name and its code, which makes getting the basics right even more important.
This is where TallyPrime can genuinely reduce the “manual pressure” of GST compliance for Rajasthan businesses. Instead of relying on repeated checks across spreadsheets and invoice templates, you can streamline the workflow from billing to filing.
Businesses can file GST returns directly from TallyPrime GST software without opening the portal. Also, if your business also deals in goods movement, TallyPrime lets you generate an e-Way Bill online while saving the invoice, and print the QR code/details where required. This is especially helpful when your sales go beyond Rajasthan.
